This 4.5″ system will give you an offroad worthy truck that you can still use as a daily driver. Not only is this system over 90% Made in the USA, this system has many advantages over the competition including new coil over struts instead of strut spacers. By replacing the struts, Zone Offroad enhances the valving to control the unsprung weight of a 33″ tire for a drastic increase in ride and handling performance over simple strut spacers. The crossmembers are made from 1/4″ thick steel and maintain a clean appearance. To gain clearance for the relocated differential, like most kits on the market, the driver’s side rear crossmember must be cut, but unlike some kits on the market, Zone Offroad includes a weld-in plate to maintain the control arm pocket’s structural integrity. In addition to a heavy duty differential skid plate that locks the two crossmembers together an additional strut bar is added on the passenger side to add rigidity and additional protection. The CNC machined ductile iron steering knuckles ensure proper steering and control arm geometry and do not limit you to 18″ or larger wheels or require you to cut off the upper control arm droop limiter like the competition. By retaining the factory droop limit, you don’t need to worry about excessive ball joint or steering component wear and be certain the system works with the trucks Stabilitrack System. The differences don’t end there, Zone Offroad only uses solid cast rear lift blocks as opposed to fabricated blocks. If you need additional rear height, Zone offers a add-a-leaf to fight spring wrap and yield additional height. Combine all of these factors and you can lock in the Zone 4.5″ system as the best value out there! Your search has ended.
